COMPENSATION OF HIGH VOLTAGE LOADS DURING PEDAL LIFT OPERATION
DRIVE
September 24, 2020
A hybrid electric vehicle or a battery electric vehicle has an electric machine, a traction battery, and an accessory powered by the traction battery. The vehicle includes a controller that, in response to a driver lifting their foot off the accelerator pedal, increases the negative motor torque produced by the electric machine for charging the traction battery to compensate for a load applied by the accessory. The controller increases negative motor torque as limited by a maximum motor torque limit. The accessory may be an electric air conditioning compressor and/or a DC/DC inverter.
